Farm animals read a thunderstorm earlier than we do — the falling pressure, the wind changing direction, the first distant rumble — and by the time the storm is overhead, cattle are restless, horses are running the fence and hens are scattering for cover that may not hold. Preparation has to happen on the forecast, not on the first flash of lightning, and it divides into three jobs: decide which animals genuinely need to be in, remove the hazards the wind creates, and make sure food and water are inside the shelter so nothing forces a mid-storm errand.
Who comes in, and who is better out
Bring under solid cover the animals a storm puts at real risk: very young stock still with their mothers, elderly animals that cannot move fast or hold condition, anything shorn recently, and any animal already unwell. Healthy adult cattle and horses in good condition often ride out a summer storm better in a field with natural shelter — a thick hedge, a belt of woodland, a dip in the ground — than in a small building they mill around in panic. What no animal should have at storm time is a lone tree to stand under, a position against wire fencing that lightning or a falling branch can bring down on them, or access to a stream bank that flash water will turn dangerous. Move stock off those spots while the weather is still calm enough to move them quietly.
Secure the yard before the wind does it for you
Walk the yard and buildings with the storm in mind. Shut and bolt stable and barn doors — a door torn off its hinges becomes a missile and leaves the building open to driven rain. Bring in or lash down the loose inventory of every yard: feed bins' lids, empty troughs, jump wings, buckets, sheet materials, the muck trailer's cover. Check the roof sheets and gutters you already suspect; a panel half-lifted by the last blow will finish its journey in this one, and it will land in a field or a pen. If a generator forms part of your backup, have fuel for it and know it starts — tested in daylight, not discovered dead by torchlight.
Feed, water and calm inside the shelter
Fill water containers in the shelters before the storm arrives and put out more forage than the night usually takes: eating is the most settling activity a ruminant or horse knows, and a full hay net keeps animals occupied through the worst noise. Bright, sudden lightning bothers some animals less with a light left on in the building, which softens the contrast of flashes, and a radio playing at low volume masks the irregular cracks with a steady human sound. Resist going in among frightened large animals at the height of the storm unless something is genuinely wrong — a calm check from the door with a torch tells you what you need without adding a body to a pen of moving cattle.
After the storm: fences first, then turnout
When the storm passes, check fences before turning animals back out — a tree across the wire or a washed-out gateway turns a routine turnout into an escape — and walk watercourses and gateways for debris before stock reach them. Storms rarely hit when the whole family is home, so the shelter list cannot live in one person's head: which field the ponies come in from, which barn the goats use, where the generator fuel sits.
